Specification of Letters Patent.

Patented July 27, 1915.

To all whom it ma concern:

Be it known that I, Jon-N GERARD, a citi zen of the United States ofAmerica, resid ing at New Britain, county of Hartford, State ofConnecticut, have invented a new and useful Door Check and Closer, ofwhich the following is a specification.

My invention relates to a door check and closer, the object being toprovide a very simple and inexpensive construction, especially useful inconnection with screen doors or other light doors.

The object of my invention is to provide an inexpensive simple andeiie'ctive construction.

In the drawings: Figure 1 is a plan view of my check and closer as itwould appear in place. Fig. 2 is a vertical section showing certainparts in elevation. Fig. 3 is a horizontal section on the line -38, Fig.2. Fig. 1 is a horizontal section on the line M, Fig. 2. Figs. 5 to 7inclusive are detail views. Fig. 8 is a detail view of a modification.

1 is a cylinder which contains a checking piston 2. 3 is a removable capat one end of the cylinder. 4 is a spindle passing through the cylinder1 and seated at its lower end in a suitable bearing in the bottom of thecylinder. The spindle 4; has a bearing in the upper part of the cylinderwhich is extended upward to form an integral sleeve-like extension 5which may have the usual packing gland 6. On the outer side of thesleeve 5 are one or more vertical ribs 7 7 which form spring holdingabutments.

8 is a helical spring having its inner end sharply turned to form a hook9 to engage one of the abutments, for example, the abutment 7, see Fig.8. The outer end of the spring 8 is curled outwardly to form a hook 10.

la -Mare arranged to be secured to the door. The piston 2 is connectedto the spindle 4 eccentric'ally, as by means of a link 17 which has atits inner end enlarged on cular passage to surround the spindle looselyOne side of the lower part or the spindle is provided with a groove 18having an inclined bottom. The eccentric proper comprises the eccentricmember 19 which is formed at its back with a key 20 adapted to fit inthe groove'lS when the parts are assembled as shown in Figs. 2, 3 and 1.The eccentric 19 is inserted in place when the spindle is turned in adirection opposite to that shown in Fig. 2. hen in position a cotter pin21 may he slipped through a hole in the part 20 and a corresponding holein the spindle at in line therewith, see Fig. 2.

In the modification shown in Fig. 1 1 provide an eccentric 22 whichfills the circular opening in the link 17 said eccentric 22 having ashoulder or flange 23 to keep it in place while the parts are beingassembled. In this instance the spindle 1 instead of being provided witha groove 18, is provided with a squared portion 18 designed to fit. intoa squared passage in the eccentric block 22. The lower end of thespindle & may be somewhat reduced as at 1* and the step in the bottom ofthe cylinder may be made of a size to receive this reduced end of thespindle.

The checking device may have the usual valved by-pass which is onlyconventionally shown herein. The piston may have the usual ball checkvalve indicated at 24, Fig. 6 to permit the piston to move back freelywhen the closer spring 8 is being wound up.

25 is a cup shaped cap arranged to slide over the closer spring 8, oneside wall of the cupped cap being provided with a slot to permit theouter end of the spring adjacent the coiled portion 10 to projectoutwardly to be engaged by the pin 10. This cap may or may not beemployed, as desired.

The parts described may be easily and cheaply manufactured and whenassembled constitute a light weight and inexpensive controlling devicefor doors, particularly useful in connection with screen doors or otherlight doors. The spring 8 may be very easily reversed without the use ofany special tools whereby the device may be apwith the outer end of thespring.

2. In a door check and closer, a checking cylinder, an extensionthereon, a checking piston arranged to reciprocate therein, a'

spindle extending diametrically across said cylinder, an eccentricconnection between the spindle and the piston, a reversible closerspring mounted on top of the cylinder and anchored at one end to saidextension, a lever arm carried by the spindle and detachably connecteddirectly with the outer end of the spring, said spring being of thehelical type with the inner end abruptly bent inwardly to engage saidextension, the outer end being bent outwardly to be engaged by the leverarm.

3. In a door check and closer, a checking cylinder,-an extensionthereon, a checking piston arranged to reciprocate therein, a spindleextending diametrically across said cylinder, an eccentric connectionbetween the spindle and the piston, a reversible closer spring mountedon top of the cylinder and anchored at one end to said extension, alever arm carried by the spindle and detachably connected directly withthe outer end of the spring, said spring being of the helical type withthe inner end abruptly bent inwardly to engage said extension, the outerend being bent outwardly to be engaged by the lever arm, said lever armhaving a rigid depending extension for engaging said outer end of thespring.

4. In a door check and closer, a checking cylinder, an extensionthereon, a checking piston arranged to reciprocate therein, a spindleextending diametrically across said cylinder, an eccentric connectionbetween the spindle and the piston, a reversible closer spring mountedon top of the cylinder and anchored at one end to said extension, alever arm carried by the spindle and detachably connected directly withthe outer end of the spring, with a groove in the side of the spindleinto which said eccentric connection projects and is detachably held.

5. In a door check and closer, a checking cylinder, a checking pistonarranged to reciprocate therein, a spindle extending diametricallyacross said cylinder an eccentric connection between the spindle and thepiston, a reversible closer spring mounted on top of the cylinder andanchored at one end to an extension therefrom, a lever arm carried bythe spindle and detachably connected with the outer end of the spring,with a groove in the side of the spindle in which said eccentricconnection is detachably held, said eccentric connection including anintegral key arranged to fit said slot.

6. In a door check, a cylinder, a piston therein, a spindle extendinginto said cylinder, an eccentric, a recess in the side of one of thelast two mentioned parts in which the other part stands, the shape ofsaid recess and the part therein preventing one part from turningindependently of the other, and an eccentric strap connection betweensaid piston and said eccentric.
